OPERATION AND MAINTENANCE –
POWER SWITCHES –
The power switch is located at the elec-
trical box behind the bottom louvered panel.
The switch will shut off all power to the cabi-
net.
TEMPERATURE CONTROL –
The temperature control is located in
the electrical box behind the bottom louvered
panel. The temperature control does not have
an ‘OFF’ position. Adjustments may be made
by the use of a screwdriver in the slot pro-
vided in the face of the control. Turning it
clockwise will give warmer temperatures
while counter-clockwis e will give colder tem-
peratures. There is also an adjus table tem-
perature differential (the difference between
the cut-in temperature and the cut-out tem-
perature) located next to the dial face.
The control has a range of –10ºF to
+50ºF with a differential of 5º to 20º. It is fac-
tory set for approximately –10ºF with a
5ºdifferential. The temperature should be
checked with a thermometer other than the
case thermometer after it is running to insure
that the cas e is running at the proper tem-
perature for the product.
THERMOMETER –
The thermometer is located in one of
the interior corners of the cabinet. The ther-
mometer will probably need resetting to re-
flect the proper case temperature. Using a
separate thermometer located on a shelf in the
case, compare this temperature to that on the
case thermometer. If the case thermometer
needs to be adjus ted, remove the clear protec-
tive cover by popping it off with a small
screwdriver and turning the small adjustment
screw on the face of the thermometer.

The thermometer will also warm up
rather rapidly when the case door is held
open for a time such as when the case is being
restocked or a shopper is making a decision
on a product. After the door is closed it will
take some time for the thermometer to pull
back down to the case temperature.
